Global Mining Review,

Silvercorp Metals Inc. has provided updates on the construction plan and progress on its new 3000 tpd flotation mill (the new mill) and tailings storage facility (TSF) at the Ying Mining District, Henan Province, China.

The plan and the required regulatory approval process to build the new mill and the TSF were announced on 16 November 2021. Currently, the company has made progress in the following areas:

  • Agreements to lease 123.46 ha. of land have been negotiated with the local community.
  • The environmental assessment report and safety assessment report for the TSF have been completed and filed with the local county government, and the reports for the new mill have been drafted and are to be finalised, pending completion of the preliminary engineering design of the new mill.
  • Seven drill rigs are currently on site and 1738 of 3300 m of foundation engineering survey drilling have been completed.
  • Contractor selection to construct 5100 m of drain tunnels at the TSF has been initiated.

The updated budget is estimated to be approximately US$29.8 million for the new mill and US$38 million for the TSF. The new mill will be equipped with a Knelson gold gravity separation circuit and designed to produce silver-lead, zinc, copper, and gold concentrates. The TSF may be constructed in two phases, with approximately 10.2 million m3 of storage capacity in Phase 1, and approximately 8.9 million m3 of capacity in Phase 2, for a total storage capacity of 19.1 million m3. The company expects that construction of the new mill will be completed by the end of 2023, and Phase 1 of the TSF by the end of 2024.

The new mill and TSF are being constructed to provide the company with additional capacity to continue growing its existing mining operations at the Ying Mining District in light of recent successful drilling programmes that have discovered new resources, to process ore from recent acquisitions, and for potential consolidation of other nearby projects. Once the new mill is completed, the company will decommission its No. 1 mill to have approximately 5000 tpd of milling capacity. A new training facility and R&D centre are planned at No. 1 mill site.
